DEVICE Fonmnarrmmc nnc'nrracnns. I

To all :wlrom it may concern:

Be it known that I, EDWARD C. CAPPER, a citizen of the United States, residing at Alpha, in the county of Fayette and State of Iowa, have invented a certain new and useful Device for Paraflining Receptacles, of which the following is a specification.

In preparing buckets, tubs and'other recepta'cles to receive butter or other substances, that are liable'to deteriorate in direct contact with the containing vessel, it is customary to apply a coat of paraffin wax or similar material to the interior of the vessel, to thereby protect the contents of the vessel from direct contact with it, and to make the vessel air and water ti ht,

My object is to provide a device of simple, durable and inexpensive construction, by which a thin, smooth, and regular coating of paraffin wax or the like, may be quickly and easily applied to the interior of buckets, tubs and other vessels.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which Figure 1 shows a vertical central sectional view of a device embodying my invention, with a vessel to be coated mounted in position on top of the device, and a vessel to be heated preparatory to applying the coating,

- mounted at the lower part of the device,

and Fig. 2 shows a top or plan view of the device embodying my invention.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the sup orting frame of the device. At the top of t e frame is a circular an 11, designed to receive parafiin, said pan aving an annular shoulder 12 formed near its central portion to receive and support the vessel to be coated. Within the bottom of the pan 11 is a steam or hot air pipe 13 communicatin at one end with a valve 15, and at its other end with a discharge pipe 16, provided with a valve 17.

Arranged near the bottom of the frame 10 is a solid platform 18 designed to receive and support an inverted tub or vessel. A pipe 19 communicates with the supply pipe 14', and has a discharge end 20 projected up- 18. This pipe 19 is provided with a valve 21 Specification of Letters Patent. Patented Aug. 4,1908. Application filed September-14, 1907. SerialNo. 392,937. I l I i i by which the passage through the pipe may.

be controlled, and mounted on the pipe 19' directly beneath the center of the pan 11 is l provided an upwardly projecting pipe 22, with a valve 23 and a nozzle 24, which latter extends through the bottom of'the pan 19 so that its discharge opening is within the pan near its bottom.

I have used the reference numeral 25 to in- 65.

dicate a tub or bucket which is of the kind in general use, and of itself forms no pa'rtof my present invention.

In practical use, I first place the vessel to be coated, in an inverted position 11 n the. platform 18, and I then'introdiice the egtlng v medium into the vessel through the pi 20, by manipulatin the valves. This it" heat the interior of t e vessel. The beating medium is also a plied at the same time to the coil 13,an d t e pan 11 is previously supplied With(a -quantity of paraffin wax, which will be hea ed by the heating medium, and in that way formed into a liquid. Thenthe heated vessel "taken from the platform 18 80.

and laced in aninverted position upon the shou der 12 of'the 11. Then the opera tor opens the valve 23 and the heating medium which is under pressure is proiected throu h the nozzle 24 and through theliquid para wax, causing the latter to be sprayed over the interior of the vessel.

By previously'heating the vessel, the paraffin wax will not harden and adhere to the vessel in a thick layer, as it would do if the vessel were cold. have found that by applying the heated liquid parafiin to a prev1 ously heated vessel, the spraying of the arafiin may be continued until every paz'ticeof the surface of the vessel is thoroughly cov-\ cred, and the coating will be than, smooth and regular throughout the entire covered surface. By having the device so anan ed that one vessel is being heated while another is being coated, the operator may readily and easily coat a comparatively large number of vessels in a short time.

Any heating medium under pressure may be used in my device, and any coating material that may be applied by melting and 1. In a device of the class described, the combination of a frame, an open topped pan out of the United States, therefor, iswardly through the. center of the platform.

I came a quantity of coating material, and also to receive and support an inverted vessel above the roatenel therein, means for applying heat to the pan to melt the coating ma terial, a nozzle projected through the bottom of the pan with its upper end below the part of the par. designed to receive a vessel, and a pipe connected with said nozzle for six plying steam under pressure to it, where f' the steam passing through the nozzle wil pass through the coating material in the pan and spray it throughout the interior of the vessel supported on the pan.

2. Ina device of the class described, the combination of a frame, a pan sup orted by the frame, a. platform su porteo by the frame, a pipe for supplying mating medium under pres ure, a (301i communicating with said pipe and resting in the bottom of said pen, a discharge nozzle communicating with said pipe and projected upwardly through the bottom of the pan, and a discharge branch communicating with the pipe and projected upwardly through the bottom of the platform, and valves for controlling the discharge of the heating medium through the i\\\\\ l said pozzle, and through the said discharge} opening. 7

' 3. In a device of the class described, the combination of a frame, a pan supported at the to of the frame and having an annular should er on its interior to supportnu invert-- ed vessel, a pipe for supplying heating medium under pressure, a coilv conummicating with said pipe and arranged within the interior of the pen, a discharge ipe conn'nunicating with said coil, a nozze communicating with the supply pipe and projected u wardly through the bottom of the pan, aso lid platform beneath the pan, a discharge pipe communicating with said supply ipe and projectcd upwardly torough the ottom of the. platform, valves for controlling the discharge through said nozzle and the discharge )ipe, and valves for controlling the passage oi the heating medium through the coil.
